Answer:
20% (pls mark me brainliest)
Step-by-step explanation:
1. you have to figure out what percentage each marble is by dividing 100 by the total amount of marbles 100 ÷ 16 = 6.25%
2. you then take that sum and you multiply it times seven because there are seven purple marbles, 6.25 x 7 = 43.75% which is the probability that you'll pick a purple marble.
3. you would then have 15 marbles so you would have to do step 1. again but with 15 substituted instead of 16, 100 ÷ 15 = 6.67%
4. after that you would do step 2. again, this time taking 6.67 and multiplying it by seven because of the seven orange marbles: 6.67 x 7 = 46.69%
5. since for this to work you would need to choose the purple one in the first place you need to figure out what 46.69% is out of 43.75%: 20.426875% which rounds down to 20%
expanding Expressions
(9x + 16 + 2) + 2x
7x14 - 2(x + 4)
x = 3+ 70% + 3) = 3x - 12
Pls help!! i will give brainly!
Answers:
1. (9x + 16 + 2) + 2x
= (9x + 18) + 2x
= 9x + 18 + 2x
= 11x + 18
2. 7 × 14 - 2(x + 4)
= 98 - 2x - 8
= 90 - 2x
3. x - 3 + 7(x + 3) - 3x - 12
= x - 3 + 7x + 21 - 3x - 12
= 5x + 6
i hope this helps! i can help to clarify anything here if you need me to

what are the coordinates of point A
A. (5,4)
B. (4,5)
C. (4,6)
D. (6,4)
Answer:
(5,4)
Step-by-step explanation:
The first coordinate is the x coordinate of the number of units we go across
x = 5
The second coordinate is the y coordinate or the number of units we go up (or down)
y = 4
(5,4)
Answer:
A. (5,4)
Step-by-step explanation:
You always put the coordinate of the X axis first which would be 5 because it is in between the 4 and 6, and on the Y axis it is in the 4 line! hope this helps! :)
Are the two outcomes listed are equally likely to occur. Give a reason for your answer.
Selecting the letter a or k from the word "TAKE"
Your answer:
Answer:
Yes. When looking at the word "TAKE" you can see that there are four letters. The probability of selecting the letter 'a' would be 1/4. The probability of selecting the letter 'k' would also be 1/4. This is because they are 1 out of 4 of the letters making up the word "TAKE". So, the outcomes are equally likely to occur.

The rectangular prism and rectangular pyramid below have the same volume. Determine the value of x, the length of the prism.
ANSWER
[tex]x[/tex]= 9 [tex]in[/tex]
EXPLANATION
The volume of a rectangular prism is given by the formula,
[tex]V[/tex]= [tex]l[/tex] x [tex]b[/tex] x [tex]h[/tex]
We substitute the dimensions to obtain,
[tex]V[/tex]= 6 x 3 x 12 [tex]in^{3}[/tex]
The volume of the rectangular pyramid is,
[tex]V[/tex]= [tex]\frac{1}{3}[/tex] x 6 x 12 x [tex]x[/tex] [tex]in^{3}[/tex]
Equating the two values gives,
[tex]\frac{1}{3}[/tex] x 6 x 12 x [tex]x[/tex] = 6 x 3 x 12
We divide through by 6×12 to get,
[tex]\frac{x}{3}[/tex] = 3
We solve for x to obtain,
[tex]x[/tex] = 3 x 3
[tex]x[/tex] = 9 [tex]in[/tex]
Hope this helps! Happy Monday!

Will the graph of y = (7.25x)^2 be stretched or compressed horizontally or vertically when compared to the parent function y = x^2?
A. Because |b| < 1, the graph will be compressed vertically.
B. Because |b| < 1, the graph will be compressed horizontally.
C. Because |b| > 1, the graph will be compressed vertically.
D. Because |b| > 1, the graph will be compressed horizontally.
The correct statement is,
⇒ Because |b| > 1, the graph will be compressed horizontally.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
Parent function is,
⇒ y = x²
And, Function is,
⇒ y = (7.25x)²
Now, The value of b = 7.25 is greater than 1.
Hence, the graph of y = (7.25x)² be compressed horizontally.
Thus, The correct statement is,
⇒ Because |b| > 1, the graph will be compressed horizontally.

10d + 20 = 100 pls answer quick
Let's solve your equation step-by-step.
10d+20=100
Step 1: Subtract 20 from both sides.
10d+20−20=100−20
10d=80
Step 2: Divide both sides by 10.
10d
/10= 80/10
so d= 80

Seth deposited $40 in a savings account that earns 5% interest each year. How much interest will he earn in 1 year?
Answer:
$2
Step-by-step explanation:
The formula for simple interest is i = p*r*t, where r is the annual interest rate expressed as a decimal fraction. Here the principal is $40 and the elapsed time is 1 year. The amount of interest collectible after 1 year is thus:
i = ($40)(0.05)(1) = $2

You are shooting baskets in gym class. You are standing about 5 ft away from the basket and the hoop is at a standard height of 10 ft. The graph of y_1 = −0.4x^2 + 10 represents this scenario. After making 10 baskets at this spot your gym teacher tells you to move to a new spot. The graph of y2 = −0.15x^2 + 10 represents your shots after the move.
Describe your new location in terms of your original location. Use the equation to explain.
A. The equations show that the absolute value of a decreased, which indicates that I moved further away from the basket.
B. The equations show that the absolute value of a increased, which indicates that I moved further away from the basket.
C. The equations show that the absolute value of a decreased, which indicates that I moved closer to the basket.
D. The equations show that the absolute value of a increased, which indicates that I moved closer to the basket.

Skills needed: Triangle Angle Measures, Solving a One-Variable Equation
1) To get the answer, you need to know that all the angles inside a triangle add up to 180 degrees. This is very important in the future as well.
2) So to find x, we can make the equation: x + 30 + 45 = 180
3) You can combine like terms:
30 and 45 can be combined --> 30 + 45 = 75
4) Based on step 3, you can get: x + 75 = 180
Subtract 75 from both sides, and you will get: x = 105

A manager samples the receipts of every fifth person who goes through the line. Out of 50 people, 4 had a mispriced item. If 1,400 people go to this store each day, how many people would you expect to have a mispriced item?
Answer:
112 people
Step-by-step explanation:
[tex]\frac{4}{50}[/tex] = [tex]\frac{x}{1400}[/tex] write the proportion where x is the number of people with a missplaced time
50x = 5600 cross multipy
x = 112 divide both sides by 50
